Michael Jackson's father told CNN's Larry King Monday night that he never beat his son or made any mistakes in raising him.

Joe Jackson also said the rumor that he wanted to take the singer's children on tour as the Jackson 3 was "a bunch of jive."

Jackson repeated his suspicion that foul play was involved in his son's death last month, but he conceded he did not know what happened. He said he had been blocked from seeing or talking to his son in the days before his death.

There were indications in the interview with Jackson, who was in Las Vegas, that he was not being included in all of the family's activities in recent weeks.

When King asked about the findings of the private autopsy -- which daughter LaToya Jackson last week said she's seen -- Joe Jackson answered "Well, they have not showed it to me, Larry. I'll put it like that."

He also said he did not know where his son's body has been kept since the memorial service.

"You'd have to ask somebody that knows," he said. "I don't know."

Jackson denied that he was legally separated from Katherine Jackson -- his wife of 60 years -- although he did say he spends most of his time in Las Vegas. His wife lives in the family home in Encino, California.

He denied a report that he had agreed to sign a document saying he would not be involved in helping raise Michael Jackson's three children as a way to help his wife retain custody of them.

"I've never said I was going to sign any papers to that effect," he said.

Debbie Rowe, Michael Jackson's ex-wife and mother of his two oldest children, has not said yet whether she will challenge Katherine Jackson for custody.

Joe Jackson appeared careful to avoid any hints that he might encourage the children to enter show business, saying "they have to be what they are, kids, at the moment."

"I can't get into that right now, Larry, because, I mean, I just can't," he said.

King asked him to respond to a media report quoting an unnamed family source that said Joe Jackson, who turned his sons into the Jackson 5, had approached Michael Jackson's children about touring next year as the Jackson 3.

"Not true. That's a bunch of jive. That's a bunch of -- I wish I could say what I should say. That's a bunch of bull."

Asked about stories that he was abusive to his son as a child, Jackson said "Oh, that's a bunch of bull S. That's a bunch of bull S."

"You never physically harmed him?" King asked.

"Never. Never have. And I -- and I raised him just like you would raise your kids, you know? But harm Michael, for what? I have no reason. That's my son. I loved him and I still love him," Jackson said.

He said he made no mistakes in raising his children.

"Michael was raised properly," he said. "He didn't run the streets like most of those other kids that was in his neighborhood."
